1. Synthesis, Antimicrobial Activity and Structure-Activity Relationship of Some 5-Arylidene-thiazolidine-2,4-dione Derivatives
Derivatives of the thiazolidine-2,4-dione core represent a heterocyclic class with several correlated properties. In this context, the synthesis of structural analogues of these bioactive substances becomes attractive in the field of medicinal chemistry. These analogues act as antimicrobial agents against Gram-positives pathogens. The present work aimed to s

9. PopulaÃÃo bacteriana, motilidade espermÃtica e fertilidade de sÃmen de piracanjuba Brycon orbignyanus, submetido ao resfriamento. / Bacterian population, sperm motility and fertility of piracanjuba semen Brycon orbignyanus (VALENCIENNES, 1849) under refrigeration.
Piracanjuba, Brycon orbignyanus, is a migratory fish species originated from the Grande River basin. Piracanjuba is currently an endangered species. As this species does not breed naturally in captivity, artificial fertilization is necessary. The aim of this study was to improve the protocols for piracanjuba semen refrigeration at 4-6Â C by pH standardizati

11. First characterization of Candida albicans by random amplified polymorphic DNA method in Nicaragua and comparison of the diagnosis methods for vaginal candidiasis in Nicaraguan women
A total of 106 women with vaginitis in Nicaragua were studied. The positive rate for the identification of Candida species was 41% (44 positive cultures out of 106 women with vaginitis). The sensitivity of microscopic examination of wet mount with the potassium hydroxide (KOH) was 61% and 70% with Gram's stain when using the culture of vaginal fluid as gold

12. Isolation of Shigellae: VIII. Comparison of Xylose Lysine Deoxycholate Agar, Hektoen Enteric Agar, Salmonella-Shigella Agar, and Eosin Methylene Blue Agar with Stool Specimens
Two enrichment broths and four plating media were compared for efficiency of detection of enteric pathogens from 1,597 stool specimens. Of 170 salmonellae isolated from the composite of all methods, direct streaking yielded but 54%, whereas enrichment in gram-negative broth found 87% and Selenite-F broth 97%. By contrast, gram-negative broth produced 100% of
